Why would I change my VRLA Batteries to Lithium batteries?

Many of our customers are now asking whether they should change their VRLA batteries to Lithium batteries, especially when replacing older systems or planning new installations.

In this blog, the battery experts at Valen Power break down the key differences between VRLA (Valve Regulated Lead Acid) and Lithium (LiFePO4 – Lithium Ferro Phosphate) battery technologies. We explain why more customers are choosing to upgrade to Lithium for better performance, reliability and long-term value.

1. Battery Safety

Valen ENLiFEN Lithium batteries are designed with a built-in Battery Management System (BMS). This internal system protects the battery from over-voltage, deep discharge, overheating and short circuits.

VRLA batteries do not have an internal BMS, which means they rely heavily on external system protection. With Lithium, you get smarter, safer battery technology built into every unit.

2. Battery Weight

Lithium batteries offer high energy density, meaning they provide more power in a smaller and lighter package.

For example:

• Valen Topin 12V 100Ah or Valen Excel 12V 100Ah battery weighs approx. 32kg

• Valen ENLiFEN 12V 100Ah battery weighs only 13kg

This weight reduction improves Workplace Health and Safety (WHS) by making batteries easier to lift, install and maintain. In many cases, there is no longer a need for cranes or heavy lifting equipment, saving time and costs during installation.

3. Custom Battery Solutions

Valen ENLiFEN Lithium batteries are fully customisable, making them ideal for both new and retrofit installations.

We can tailor:

• Voltage and capacity

• Case size and type

• Terminal connections

• BMS features

Customising the battery to suit your application ensures a perfect fit and maximises battery performance and service life. This flexibility makes Lithium ideal for applications where traditional VRLA batteries simply won’t fit.

4. Battery Life Span

Lithium batteries have a much longer design life than VRLA batteries, especially in demanding environments. This extended life makes them ideal for both cyclic and standby power applications, where performance and reliability are critical.

By reducing the frequency of battery replacements, Lithium helps lower long-term operational costs.

5. Performance in Extreme Conditions

Temperature is one of the most important factors affecting battery life.

• VRLA batteries perform best between 20°C and 25°C. For every 8°C increase above 25°C, the battery life is halved

• Lithium batteries operate reliably in a wide range from -20°C to 60°C

This makes Valen ENLiFEN Lithium batteries ideal for remote, outdoor or temperature-sensitive sites. Their ability to withstand extreme heat and cold reduces the risk of failure and extends their service life.

6. Long-Term Cost Benefits

While the upfront cost of Lithium batteries may be higher, the long-term savings are significant. Lithium reduces the need for:

• Frequent battery replacements

• Ongoing maintenance

• Expensive site visits to remote locations

Over the life of the battery, Lithium is a more cost-effective and reliable choice, especially in critical or hard-to-access installations.
